I made this box for my 1st outing last month, knowing I would need something for the beach sand & not having anything available. I had the materials lying around in storage, some extra cabinet handles, chicken wire, wood and some nails. It has worked great for me since I go with my son. I dig with a large plastic scoop into it and he sifts. I am going to be getting/making something else that would be more practical for the days that he won't go and I'll be solo. The dimensions are 15 X10". I think that if I were making it again I would go a little smaller...maybe 13 x 9".
